You can't query whether (if modular build is done) the audio backend driver is actually installed. In your case it would be done by: { "query-audiodevs/ret-type/+pipewire", QEMU_CAPS_QUERY_AUDIODEVS_PIPEWIRE } and would require a new capability dump. I can do the latter if you want. Given that here it's only a explicit user configuration, I don't think it's entirely necessary to have capability checks.
